PATENT I DENNIE M. DORMAN, OE BINGHAMTON, NE1V YORK.

ACETYLENE-GAS GENERATOR.

SPECIFICATiQN forming part of Letters Patent No. 634,401, dated October3, 1899. Application filed January '7, 1899. $erial No. 701,479. (Nomodel.)

To all whom it may concern:

Be it known that I, DENNIE M. DORMAN, a citizen of the United States,residing at Binghamton, in the county of Brooms and State of New York,have invented new and useful Improvements in Acetylene-Gas Generators,of which the following is a specification.

My invention relates to an improved acetylene-gas generator.

An object of my invention is to provide improved means for discharginggiven quantities of carbid into the generating-chamber.

A further object of the invention is to provide improved meansautomatically operated to discharge given quantities of carbid into thegenerating-chamber at intervals determined by the consumption of the gasgenerated.

A still further object of the invention relates to certain details ofconstruction and operation of the parts whereby I aim tojproduce acompact, simple, and easily-operated device of the character indicated.

I have illustrated my invention in the accompanying drawings, in which-Figure 1 is a view in side elevation of the complete device. Fig. 2 is alongitudinal sectional view, and Fig. 3 is a detail view of one of thecartridge-shells.

The numeral 1 indicates the outer shell or casing of the apparatus,which in conjunction with a bell 2, mounted ,in the casing 1 in theusual manner, affords in its upper por- In the lower portion of the tiona gas-holder. casing 1 is located a closed receptacle 3, adapted tocontain water and affording a generating -chamber, which is secured tothe side wall of the casing in any suitable manner and from the upperside of which apipe l extends to the top of the gas-holder for conveyingthe generated gas thereto. Located in the pipe 4 is a valve 5, suitablyoperated from a handle 6 to close communication between the gasholderand generating-chamber.

The numeral 7 indicates a supply-pipe leading from the top of thegas-holder to convey the gas to the bu'rners.- Leading from the bottomof the generating-chamber 3 and extending through the casing 1 is a pipe8, having a valve 9, by opening which valve the pressure of the gas maybe utilized to discharge the spent carbid from the generating-chamber.

The numeral 11 indicates a chute, the bottom of which is secured uponand communicates with a curved branch pipe or conduit 12, bolted to thecasing near the bottom there of and communicating through the casing andthe wall of the generating-chamber with the interior of the latter. Thewater in the generating-chamber riseshigh enough in the pipe 12, asshown, to afford a liquid seal. A-pipe 13, having a valve 14:, affordsmeans for supplying water to the generating-chamber. I have shown inFig. 1 the chute 11 as being inclined for the purpose of accommodating alarger number of cartridges where the height of the chamber in which theapparatus may be located is not sufficient to permit the chute to risethe requisite distance. In either case the top of the chute ishermetically closed by a suitable cover 15.

The numeral 16 indicates a screen secured above the bottom of thegenerating-chamber to support the cartridges above the spent carbid,which settles in the bottom of said chamber.

Rotatably mounted in the bottom of chute 11 by means of journals 18 is ahalf-round bucket or receptacle 19, which is of a size to receive ashell 17 and the opening 20 of which is designed to be turned by themechanism now to be described to a position to receive the lowermostcartridge in the chute and then to a position to discharge the same intothe pipe or conduit 12; Secured on the outer end of a journal 18 at theouter side of chute 11 is a pinion 21, which meshes with a rack 22,provided at the lower end of a bar 23. Atits upper end the bar 23 isprovided with a number of apertures 24, by means of which it may beadjustably secured to an arm 25, carried by the bell 2. A series ofguides 10, secured on the casing 1, guides the arm 23 as it is carriedup and down by the movement of the bell. It will be seen that as thebell 2 rises or falls the corresponding movement of the arm 23 will,through the medium of rack 22 and pinion 21, revolve or turn the bucket19 inone direction or the other.. The adjustment of this arm with thebell is such thatas the gasis consumed and the bell falls apredetermined distance, at which point a fresh generation of gas will berequired, the

bucket 19 will be turned to bringits opening" 20 over the opening inpipe 12,whereby a shell 17, containing earbid, may be discharged intothe generating-chamber 3. As gas generates the bell rises and the bucket19 is turned in the reverse direction to bring its opening 20 in aposition to receive a fresh cartridge.

While I have shown no means for limiting the upward movement of bell 2,it is obvious that any well-known means may be employed to prevent therise of the bell beyond a predetermined point.

The shells 17 are of metal and are in the form of cylinders having openends. After a shell 17 has been packed with carbid its ends are closedby means of metal disks 26, inserted therein, which are of a size to beheld in the shell by frictional engagement therewith. These disks areconnected by a chain 27, extending through the shell 17 and somewhatlonger than the shell, and each disk is provided with an aperture 28,through which water can enter to the carbid. As the water contacts withthe earbid in the shell the gas generated will blow the disks out of theshell; but the chain 27 will hold the disks and prevent them from beingdisconnected entirely from their shell.

The numeral 29 indicates a manhole, by means of which access may behadto the generating-chamber to remove the shells therefrom. Before themanhole is opened the valve 5 in pipe I would of course be closed.

Having thus fullydeseribed my invention, what I claim as new is 1. In anacetylene-gas generator, the COIIlbination with a generating-chamber, ofa gasholder having a movable hell, a chute having communication withsaid generating-chamber and adapted to contain a number ofcarbid-cartridges, a bucket journaled in the bottom of said chute, apinion secured on the journal of said bucket and a rack-bar carried bysaid bell and meshing with said pinion, the combination operating as setforth.

2. In an acetylene-gas generator, the combination with agenerating-chamber, of a gasholder having a movable bell, a chute havingcommunication with said generating-chamber and adapted to contain anumber of earbid-eartridges, a bucket journaled in the botjournal ofsaid bucket and a rack-bar carried by and having adjustable connectionwith said bell and meshing with said pinion, the combination operatingas set forth.

3. In an acetylene-gas generator, the combination with a casing having ageneratingchamber in its lower portion, of a movable bell mounted insaid casing and affording, in connection therewith, a gas-holder, avalved pipe affording communication between said i generating-chamberand bell, an upwardlycurved pipe or conduit secured to said casing andcommunicating through the same with the generating-chamber, whereby thewater in said generating-chamber will rise in said pipe or conduit toafford a liquid seal, a chute secured to and communicating with saidpipe or conduit, a bucket journaled in the lower part of said chute, apinion secured to the journal of said bucket andarack-bar carried bysaid bell and meshing with said pinion, the combination operating as setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
